Referring to Fig. 4, in one exemplary embodiment, a kind of information recommendation method is suitable for implementation environment shown in Fig. 1
The structure of server-side 200, the server-side 200 can be as shown in Figure 3.
This kind of information recommendation method can be executed by server-side 200, may comprise steps of:
Step 310, server-side obtains information.
Information can be text information, video information, merchandise news etc., and the present embodiment does not make the type of information specific
It limits.Different application scenarios can be corresponded to accordingly, due to the different type of information, are read for example, text information can correspond to news
Scene is read, video information can correspond to video-see scene, and merchandise news can correspond to shopping scene, and therefore, the present embodiment is provided
Information recommendation method can according to the different type of information be suitable for different application scenarios.
For server-side, information will be got by different information sources according to the different type of information.For example, literary
The various topics that this information can be issued in forum, video information can derive from the public platform of Domestic News class, commodity letter
Breath can the e-commerce platform etc. built of source Mr. Yu market.
After obtaining information, just it can be sorted out for information, to provide information recommendation service to client.
Step 330, the interest point name carried to information identifies, obtains interest point name segment.
Point of interest (POI, Point of Interest) is related with geographical location, can be used for terrestrial reference in map, sight spot etc.
Mark, in order to which server-side can provide a user location information service according to point of interest, for example, geographical location query service.
Point of interest includes but is not limited to title, classification, longitude, latitude, affiliated zoning, affiliated commercial circle etc..Correspondingly, interest point name
Segment then refers to the interest point name that information carries.
For example, a specific point of interest M is: entitled " restaurant M ", classification are " food and beverage sevice ", longitude is " X ", latitude
Degree is " Y ", affiliated zoning is " area the city A C ", affiliated commercial circle is " commercial circle Z ".Assuming that including interest point name " M meal in information
Shop ", then " restaurant M " is considered as interest point name segment.
Further, information includes but is not limited to information header, information content etc., and interest point name can be needle in identifying
Information header is carried out, is also possible to for the information content, can also be emerging to what is carried in information header and the information content
Interest point title is identified, is not limited herein.
For example, information is video information, which includes video title and video content, it is assumed that video title carries
Interesting point title " restaurant M ", then identify to obtain interest point name segment by the interest point name for carrying out the video title
For " restaurant M ".
Or information is merchandise news, which includes product name and commodity details, it is assumed that in commodity details
It describes the commodity and belongs to the food sold fast in the restaurant M, then the knowledge carried out by the interest point name for including to the commodity details
Not, it is " restaurant M " that interest point name segment, which can be obtained,.
Step 350, matching retrieval is carried out in the point of interest of storage according to interest point name segment, obtains title and interest
The point of interest that point name segment matches.
In server-side, it will be stored for the point of interest of magnanimity, so as to based on the point of interest mark carried out in map
It infuses and provides a user the services such as geographical location inquiry, positioning.
It is appreciated that it is different to store the point of interest title that is included in server-side, as a result, in order to obtain title with it is emerging
The point of interest that interest point name segment matches, then need the foundation using interest point name segment as matching retrieval.
For example, interest point name segment is " restaurant M ", then it, just can be by the point of interest of magnanimity by matching retrieval
Allot the point of interest M in entitled " restaurant M ".
Step 370, interest point name segment is obtained to match the commercial circle attribute of point of interest.
Commercial circle attribute is used to indicate some commercial circle, suitable for different application scenarios.For example, the commercial circle attribute of point of interest
It is then the instruction affiliated commercial circle of point of interest, and for a user, commercial circle attribute then indicates commercial circle where user.
For the commercial circle attribute of point of interest for characterizing the affiliated commercial circle of point of interest, the affiliated commercial circle of the point of interest can be only by the interest
Point composition, is also possible to also include other associated points of interest, not be limited herein.Wherein, it is associated and refers to it
His point of interest and the point of interest belong to same zoning, alternatively, other points of interest are within the scope of the point of interest periphery distance to a declared goal, again
Alternatively, other points of interest and the point of interest belong to same category and are located within the scope of the distance to a declared goal of periphery, for example, 500 meters.
It should be appreciated that point of interest can include belonging to commercial circle information, can also only indicate food and drink near it,
The relevant informations such as shopping.Therefore, it if point of interest has included affiliated commercial circle, can directly extract to obtain the commercial circle of point of interest
Attribute.
If point of interest do not include belonging to commercial circle information, can according to indicated by it near food and drink, shopping etc.
It further refines to obtain commercial circle attribute in relevant information.For example, point of interest indicates that it nearby has " restaurant M ", and " restaurant M " is located at
The commercial circle Z, " commercial circle Z " is considered as the commercial circle attribute of the point of interest as a result,.
Certainly, in other embodiments, commercial circle attribute can also be carried out for point of interest and other associated points of interest
It is pre-configured with, correspondingly, the commercial circle attribute of point of interest and other associated points of interest is the commercial circle attribute of configuration.
For example, point of interest J and point of interest K does not include the information of affiliated commercial circle, since the classification of the two belongs to " meal
Drink-service business ", and within the scope of 500 meters of the periphery in " restaurant M ", then commercial circle Z where being pre-configured with " restaurant M " as point of interest J with
The commercial circle attribute of point of interest K, when carrying out the acquisition of point of interest commercial circle attribute as a result, the commercial circle attribute of point of interest J and point of interest K are
For " commercial circle Z ".
Step 390, the classification that information is carried out according to commercial circle attribute, the letter of commercial circle where providing user by the information of classification
Breath is recommended.
After getting the commercial circle attribute of point of interest, just information can be sorted out based on the commercial circle attribute, i.e., with
Commercial circle attribute is as the information category for being classified information.
For a user, commercial circle attribute indicates commercial circle where user, as a result, when client passes through user geographical location
When positioning and initiating to request to server-side, server-side just can carry out information recommendation according to the user geographical location navigated to.
For example, user geographical location indicates that user is located in the commercial circle Z, correspondingly, server-side will be " Z according to commercial circle attribute
Commercial circle " to user's pushed information classification be " commercial circle Z " information.Wherein, information category is that the information of " commercial circle Z " can refer to hair
If the raw Domestic News in " commercial circle Z ", can also refer to the commodity in " commercial circle Z " hot buy, or heat is chatted in " commercial circle Z "
Topic etc..
By process as described above, the localization for realizing information is sorted out, so that the information based on commercial circle attribute
Recommending can be closely related with commercial circle where user, with this enhancement information correlation.
In addition, commercial circle where the value volume and range of product of information to be recommended zoning where user is contracted to user, subtracts significantly
The value volume and range of product for having lacked information to be recommended is conducive to the recommendation efficiency for improving information.
Referring to Fig. 5, in one exemplary embodiment, step 330 may comprise steps of:
Step 331, interest point name matching is carried out according to interest point name dictionary in the information, obtains calling the roll comprising interest
At least text fragments claimed.
Interest point name dictionary, it can be understood as it is the set of the title of magnanimity point of interest, interest point name as a result,
Match, be then that interest point name entrained by the title and information by magnanimity point of interest compares, is obtained with this comprising point of interest
The text fragments of title.
It is appreciated that the possible more than one of interest point name entrained by information, therefore, the text comprising interest point name
The quantity of segment is at least one.
Further, in interest point name matching, text fragments comprising interest in addition to will also call the roll comprising interest point name
The preceding suffix information claimed.
For example, including " the Emperor Qin Huairou four seas " in information, then the text fragments matched comprising interest in addition to calling the roll
Claim " Huairou ", also by comprising the word adjacent with the interest point name, i.e., before suffix information " Emperor Qin ", " four seas ".
After obtaining text fragments, the foundation that just can be identified in this, as interest point name passes through interest point name
And its semantic relation between preceding suffix information effectively ensures the precision of subsequent interest point name identification.
Step 333, relevance ranking is carried out to the interest point name in an at least text fragments.
Due to the text fragments comprising interest point name quantity may there are two or more, in order to improve interest point name
The efficiency of identification, and then guarantee the precision of interest point name identification, it will be for the point of interest in two or more text fragments
Title carries out relevance ranking, to obtain the included highest text fragments of interest point name correlation, and is directed to this article this film
The subsequent interest point name identification of Duan Jinhang.
For example, the interest point name that a text fragments include is " Beijing East 2nd Ring Road ", another text fragments includes
Interest point name is " Oriental Pearl's tower ", it is seen then that the correlation of above-mentioned two interest point name is very low.Assuming that there are one texts
The interest point name that segment includes is " Shanghai Lujiazui ", at this point, interest point name " Oriental Pearl's tower " and interest point name " on
Extra large Lujiazui " is considered as that correlation is higher, then carry out interest point name identification will not be include interest point name " Beijing east two
The text fragments of ring ".For interest point name " Oriental Pearl's tower " and interest point name " Shanghai Lujiazui ", by further
Correlation calculations will obtain the highest interest point name of correlation, and obtain included interest point name correlation highest with this
Text fragments.
For example, the correlation of the interest point name carried in information header, which is lower than in the information content, to be carried in correlation calculations
Interest point name, interest point name be a certain specific landscape correlation be higher than interest point name be a certain zoning.
By above-mentioned realization process, text fragments corresponding to the highest interest point name of correlation can carry out interest
The identification of point title not only contributes to reduction system processing task amount, improves system treatment effeciency, and advantageously ensure that interest
The precision of point title identification.
Step 335, the included highest text fragments of interest point name correlation are identified using Named Entity Extraction Model,
Obtain interest point name segment.
Assuming that the highest interest point name of correlation is " Oriental Pearl's tower ", then corresponds to text fragments and know by name entity
The interest point name segment that other model identifies is " Oriental Pearl's tower ".
Wherein, Named Entity Extraction Model is obtained according to suffix information training before point of interest and/or geographical location.
Specifically, by obtain magnanimity point of interest and/or geographical location before suffix information (for example, being located at, place, big
Tall building, Technology Park etc.) it is used as training data, and mark and to form trained set, name Entity recognition network, Jin Erli are constructed with this
It is named the training of entity recognition model with neural network model, thus obtains Named Entity Extraction Model.
In above process, the generation of word in identification process, word, sentence, and benefit are enhanced using the point of interest of magnanimity
Sew the semanteme in information refinement identification process between interest point name and its preceding suffix information with the relevant front and back in geographical location
Relationship, so as to improve the precision of interest point name identification.

The training of formula further improves the precision of interest point name identification with this.
It is illustrated by taking the text fragments in " the Emperor Qin Huairou four seas " as an example, letter is sewed with interest point name " Huairou ", front and back
The input of " Emperor Qin " and " four seas " as Named Entity Extraction Model is ceased, before and after magnanimity point of interest and/or geographical location
Sew name Entity recognition network constructed by information, i.e. confirmation text segment does not carry interest point name, eliminates with this
There are the interest point name of ambiguity and its preceding suffix informations for semantic relation.
Under the action of above-described embodiment, the precision of point of interest identification is effectively improved, ensure that interest point name piece
The accuracy of section is conducive to ensure the accuracy that subsequent point of interest commercial circle attribute obtains, and then improves the precision of information recommendation.
Referring to Fig. 6, in one exemplary embodiment, point of interest does not include the information of affiliated commercial circle, commercial circle attribute
Acquisition process be pre-configured with it is related.
Correspondingly, step 370 may comprise steps of:
Step 371, matched by interest point name segment and extract location information in point of interest, and the position extracted is believed
Breath is converted to property index value.
As previously mentioned, point of interest includes but is not limited to title, classification, longitude, latitude, affiliated zoning, affiliated commercial circle etc..
Therefore, longitude, latitude, affiliated zoning can include but is not limited to by the location information extracted in point of interest.
Property index value and commercial circle attribute have index relative, are used to uniquely identify commercial circle.That is, a quotient
Enclose the corresponding property index value in commercial circle indicated by attribute.For example, commercial circle attribute is " commercial circle Z ", corresponding property index value
It is 1, by the index relative between property index value and commercial circle attribute, commercial circle attribute just can be indexed by property index value 1
For " commercial circle Z ".
As shown in fig. 7, in an embodiment in the specific implementation, index relative between property index value and commercial circle attribute
Building process may comprise steps of:
Step 410, region unit division is carried out to the affiliated zoning of the point of interest of storage according to specified region unit parameter, to divide

Step 430, commercial circle attribute configuration is carried out to region unit according to the point of interest in region unit.
Step 450, the index relative between property index value and commercial circle attribute is constructed.
It is appreciated that the point of interest of storage is magnanimity, then the affiliated zoning of magnanimity point of interest then may be entire China, or
The entire Asia of person.For this purpose, in order to improve the information correlativity of recommendation information, it, will be right also for the recommendation efficiency for improving information
The affiliated zoning of magnanimity point of interest is finely divided.
Specifically, specified region unit parameter can be region number of blocks, region block size can also be, for example, 100 meters
× 100 meters, herein without limiting.
Region unit division is carried out according to specified region unit parameter, the affiliated zoning of magnanimity point of interest is divided into multiple regions
Block, and the configuration of property index value is carried out for multiple regions block.More preferably, according to the geographical location relationship between each region unit, according to
Dispose to sequence property index value.
Due to magnanimity point of interest random distribution, region unit may include one and the above point of interest, be also possible to not
Include point of interest.
For the region unit comprising point of interest, commercial circle will be carried out according to the classification of point of interest, affiliated commercial circle etc. in region unit
The configuration of attribute.For example, the property index value that certain region unit is configured is 1, point of interest M is contained in the region unit, point of interest M
Affiliated commercial circle be " commercial circle Z ", then the commercial circle attribute that the region unit is configured be " commercial circle Z ", and with this construct property index value 1 with
Index relative between commercial circle attribute " commercial circle Z ".Correspondingly, the commercial circle attribute for being under the jurisdiction of other points of interest of the region unit also regards
For " commercial circle Z ".
After completing the configuration of property index value and commercial circle attribute, the point of interest in region unit all has corresponding attribute
Index value and commercial circle attribute just can index to obtain quotient after learning point of interest based on this according to corresponding property index value
Enclose attribute.
Further, for the region unit for not including point of interest, attribute will be drawn according to zoning configuring area where region unit, and
The index relative between property index value and zoning attribute is constructed with this.Wherein, zoning attribute indicates some zoning.
That is, property index value is equipped with for each region unit, for the region unit comprising point of interest
For, it is configured for commercial circle attribute, and for the region unit for not including point of interest, then it is configured with zoning attribute, is based on structure as a result,
The index relative built, property index value or index obtain commercial circle attribute or index obtains zoning attribute, and then just can be with
This is the information according to commercial circle where recommending it to user, alternatively, the information of zoning where it.
Step 373, commercial circle attribute is obtained according to the index relative between property index value and commercial circle attribute.
